摘要： The expandable tools disclosed herein may be used as an underreamer to enlarge a borehole, or may be used to stabilize a drilling system in a previously underreamed borehole or in a borehole that is being underreamed while drilling progresses. At least one moveable arm, which translates between a collapsed and expanded position in response to a differential pressure between the axial flowbore and the wellbore, includes a borehole-engaging surface with cutting elements and at least one nozzle to direct a fluid across the borehole-engaging surface. Flow directing elements on the external surface of the tool may be used to decrease the flow area in an annulus between the tool and the wellbore and directs fluid flow in the annulus toward the borehole-engaging surface.

摘要： Various embodiments of an expandable downhole tool for use in drilling of a wellbore are disclosed. The expandable tools disclosed herein may be used as an underreamer to enlarge a borehole, or may be used to stabilize a drilling system in a previously underreamed borehole or in a borehole that is being underreamed while drilling progresses. The various embodiments of the expandable tools disclosed herein have a higher hydraulic capacity than prior art underreamers. An increase in hydraulic energy delivered to the cutting structures may advantageously improve the rate of removal of cuttings from the cutting structures (improved cuttings evacuation), may decrease cutter element wear, and may prevent damage or premature failure. Improved cuttings evacuation may also provide for improved cutting action and increased penetration rates.
摘要翻译：公开了用于钻井中的可扩展井下工具的各种实施例。本文公开的可膨胀工具可以用作扩孔器的扩孔器，或者可以用于稳定钻井系统在预先钻进的钻孔中或在钻孔进行时正在被加热的钻孔中。本文公开的可膨胀工具的各种实施例具有比现有技术的扩孔器更高的液压能力。输送到切割结构的液压能量的增加可以有利地提高切割结构的切割速度（改进的切屑排出），可以减少切割器元件磨损，并且可以防止损坏或过早失效。改进的切屑撤离也可以提供改进的切割作用和增加的渗透速率。

摘要： The retrieval tool includes a cylindrical member having a body, an inner passage, a guide cylinder and an engaging member. The engaging member may slide within the cylindrical member in order to frictionally engage a whipstock against an inner surface of the guide cylinder, facilitating removal of the whipstock from a borehole. A actuating member, piston, retainer and swivel sub may be used to connect the engaging member to the retrieval tool and enhance the mobility of the engaging member within the cylindrical member. A spring may also facilitate locking engagement of the engaging member and whipstock. Contact between the retrieval tool and the whipstock may lead to an increase of pressure within the inner passage, such pressure increasing the engagement between the engaging member and whipstock.
